Ligterink, N.E. (author), Kraan, T.C. (author), Eijk, A.R.A. (author)The Dutch national transport CO2 emissions are determined by summing individual cases: a particular vehicle, on a particular road and traffic situation. In this paper the different aspects and the relations among them, as used in emission predictions, are outlined. In particular the central role that the CO2 type-approval value (from the NEDC...conference paper 2012

Wessels, P.W. (author), Basten, T.G.H. (author), van der Eerden, F.J.M. (author), Graafland, F. (author)Developments in systems for monitoring environmental noise have made it possible to monitor the acoustic situation within large urban areas. The developments in hardware size and costs, combined with the developments in wireless communication allow to deploy networks with many acoustic sensors without much effort. An application of such a sensor...conference paper 2014

Dittrich, M.G. (author), Jansen, H.W. (author)Improved methods for measuring curve squeal and braking noise have been proposed within the ACOUTRAIN project, intended as input to future standards. In this paper an outline of these methods is given and the underlying considerations are explained.

Ligterink, N.E. (author), Eijk, A.R.A. (author)Since 2008 Travelcard Nederland BV and TNO collaborate to determine the real-world fuel consumption of modern vehicles. The difference between the official type-approval value and the actual fuel consumption has been reported over the years (Ligterink, 2010 and Ligterink, 2013 and Ligterink, 2014). The fact that both numbers do not coincide is...conference paper 2014

Mentink, P.R. (author), Willems, F.P.T. (author), Kupper, F. (author), van den Eijnden, E.A.C. (author)This paper presents a model-based control and calibration design method for online cost-based optimization of engine-aftertreatment operation under all operating conditions. The so-called Integrated Emission Management (IEM) strategy online minimizes the fuel and AbBlue consumption. Based on the actual state of engine and aftertreatment systems,...conference paper 2013

Klunder, G.A. (author), Wilmink, I.R. (author), TNO Bouw (author)This paper investigates the possibility to decide when to apply a (dynamic) traffic management measure to improve the air quality or reduce CO2 emissions, based on a limited set of (measured) data. It is expected that a combination of monitoring and modeling is needed for reliable air quality estimations. Improvements in traffic and emission...conference paper 2009

Lei, C. (author), van Eenennaam, E.M. (author), Klein Wolterink, W. (author), Karagiannis, G. (author), Heijenk, G. (author), Ploeg, J. (author)Recent development in wireless technology enables communication between vehicles. The concept of Co-operative Adaptive Cruise Control (CACC) which uses wireless communication between vehicles aims at string stable behaviour in a platoon of vehicles. "String stability" means any non-zero position, speed, and acceleration errors of an individual...conference paper 2011

Semsar Kazerooni, E. (author), Ploeg, J. (author)This paper presents the interaction protocols developed for execution of two common scenarios in daily traffic using cooperative automated vehicles. The first proposed scenario addresses merging of a (semi-)automated car on a highway within a platoon of (semi-)automated vehicles. The second scenario is an extension of the first scenario with a...conference paper 2015

van Schijndel-de Nooij, M. (author), de Hair-Buijssen, S.H.H.M. (author), Verweij, R. (author), Mathevon, V. (author)In the Netherlands, annually 185 cyclists and 70 pedestrians are killed in traffic accidents, half of which due to an accident with a passenger car. The project SaveCAP runs a Sensor Field Test on vehicle safety systems designed to protect cyclists and pedestrians, either by avoiding an accident or by actions such as deploying a windshield...conference paper 2011

Dittrich, M.G. (author), Létourneaux, F. (author), Dupuis, H. (author)A measurement method for combined roughness, track decay rates and transfer functions derived from rail vibration during a train pass-by was initially developed in the late nineties [1]. This method has been then later implemented in software tools [2] and applied in several countries for various purposes [3][4][5]. Due to the wide application...conference paper 2013

Straten, T.F.J.M. (author), van den Berk, J.A.M. (author)The next generation off-road vehicles will see additional exhaust gas aftertreatment systems, ranging from DOC-SCR only to full DOC-DPF-SCR-AMOX systems. This will increase system complexity and development effort significantly. Emission requirements and the high number of vehicle configurations within the off-road industry will require a new...conference paper 2011

Dittrich, M.G. (author)Track decay rates are measured to characterize the track dynamics for railway noise type testing, but also for other purposes in relation to railway noise. They are often measured statically using hammer response functions on unloaded track, but can also be derived from rail vibrations on loaded track during a train pass-by. There are several...conference paper 2012

(author), TNO Bouw (author)One of the goals of the European IMAGINE project, is to formulate strategies to improve traffic modelling for application in noise mapping. It is well known that the specific deceleration and acceleration dynamics of traffic at junctions can influence local noise emission. However, macroscopic traffic models do not always model intersections,...conference paper 2006
